C4 - OW to Left in Hole

This is a moderately long OW with tighter-than-knee crux up a bit.

Ground rules for 10a: sit start. Use ledge on the left for your feet but no hands out of the crack.

Ground rules for 10c/d: sit start. Use your feet and hands only in the crack.

Walk/squeeze into the hole from the east. This is the southern crack.

None. You can bridge across to the opposite side of slot/chimney if not comfortable.
